Overall, it is excellent for the price they charge.
I lived in a 14-bed room, including lockers for each person, two washrooms and two showers. The room was clean.
For the 14 bed room, there's no table or chair. Nevertheless, before entering the bedroom, there's a small lounge outside, which is kinda nice if you need a seat or not wanna to bother others.
For the shower, I wish there was an additional rack beside the sink cause I couldn't find a place to put all the things I need. In addition, the hair dryer is kinda loud and not so strong to dry hair; I hope they can install a better one.
I think The Clarence Park is a great Hostel, and I will definitely come back if I come to Toronto in the future! The only thing I think needs to be considered is the not so good noise insulation. Especially having the possibility of living with 13 other guests who have different schedules. A little sound can wake you up at night! If someone is taking a shower at night, like 12 am, you can hear it!!!
They also have a common kitchen with shared kitchenware and fridge to store any food you have. Breakfast is also served from 8-10am. However, breakfast is nothing fancy but cereals and toast with butter or jam. Also, the milk for cereal went out so fast; I was there at about 8:40, and the milk was already gone.
